Wiring of RSX Widebands into the KPro/S2000.
Some history. When we developed the KPro/S2000 board we made it compatible with both stock narrowband and RSX wideband oxygen sensors. At product release we (Hondata) felt that the risk of damage to the ECU from re-wiring the oxygen sensor was too great, given our experience of end user wiring success rates, and so did not announce support for the RSX wideband. Another factor was that you could purchase a wideband sensor and controller for only $50 more than the cost of the RSX sensor, and have something which worked better than the RSX sensor. However, we left the wiring on the the adapter board for the wideband sensor. This is an unsupported feature which we have been happy to live with for the last three years, but now we may need to remove this wiring from adapter boards as we are the ones who pay for others mistakes.
Be aware that any wiring fault may damage your ECU and/or adapter board. Be aware than certain wiring faults will render useless your ECU and adapter board with a 100% rate of destruction. If you manage to apply battery voltage to any of the ECU ground wires then you end up with a 7-8 volt reverse polarity for all the 5V components in the ECU. This is about 25 times what a typical 5V component can stand in reverse polarity, so there is almost a 100% change of damaging the bulk of the ICs in the ECU.
Don't attempt this project unless you are confident enough that you have the correct parts and that you can perform the wiring changes without the possibility of single error.

So FYI, this is due to me guys. I had the setup running for a week or so and then out of nowhere the ECU burnt crispy, big time. The issue with the wideband I had before even stopped, but then a day or so later it just went to shit. I can't blame Hondata for this cuz it is an unsupported mod and I took my own risks and now I pay the price. But I do have to call some BS on this official post though. 3 years, according to them, they have had this on there, and I have a very detailed email from them telling me how this is a potential (and likely) disaster, according to them, but I dont think I have ever seen an actual post up about it, ive seen them post on here about this, but never on the precise technical hazards of this install. Kinda shitty if you ask me, if you can take the time to post on a board, you can take the time to throw out some actual tech info, especially when you are charging nearly 2k for your product.
My other issue is that they state they will have to take this feature out, evidently because it is they who pay for others mistakes. Well they aren't paying for my mistake, so I'm not really sure where that's coming from, because according them I hooked up an unsupported sensor and to get it fixed I have to send them a new RSX ECU, the burnt crap I have, and $400. My other problem stems from the last statement, "Don't attempt this project unless you are confident enough that you have the correct parts and that you can perform the wiring changes without the possibility of single error." Me and Justin were quite confident we had all the correct parts, but I am sorry, there is no way you can be 100% positive there are no errors, especially in wiring that you can't even observe internally. If there was, nobody would even bother having a warranty. So, just be warned that it seems that adding this sensor CAN, in a very odd chance, rape ur shit, and Hondata will offer you no help. Good times

and what does that mean that the feature will be taken out? future hardware won't contain the ability? or the software will be adjusted to not let current users use it?

We're sorry you have had this problem, but believe that our statement above was reasonable. This does cost us; not in the least from people who do not tell us what they have done to damage their ECU but still expect it to be covered under warranty replacement.

Well since he didn't send it into you, I would say you didn't spend but a little email time looking at some photos. The point is you haven't even looked at your PCB to see if it was in fact something you did. The PCB in this ECU is revision 7. The first S2000 kpro ecu I got had revision 2 board on it, so apparently you have made mistakes and had to fix them at some point. The wiring is the same as I am running with no problems. I will double check everything for a third time, but assumming you guys didn't reroute something the sensor should have worked. The ecu did not just fail out of the blue, it failed after uploading a calibration to the ecu, seems kind of odd that it did it right after an upload.
It isn't like you haven't cost owners money before, I remember whenever you realeased a bad version of kmanager and it broke all the vtec solenoids on the rsx. My friend spent a lot of money ordering a new solenoid only to find out your crummy software realease is what created the problem.
You act like you guys never mess up or do anything outside of "supported" things. You technically are reverse engineering a Honda ECU to create a product. That alone comes with risk. If you are not building in time to handle various issues with your product then you are not a realistic business person. If you did in fact create this product it wouldn't be a huge issue and you could just repair it, but since you stole someone elses design and are "modding" it to work you can't 100% say that it wasn't a defect in the ecu. Especially since it was a brand new ecu.
I also like how you think that you know what people will spend on features of a product. It it were all about money then obviously non of us would bother buying this product as it is extremely expensive for a product that isn't even created by you. It is just a hack board to another product that is more than a completely engineered solution.
